1967. 400 pp. Fine hardcover, in a Very Good dust jacket. Dust jacket would be in Fine condition, but there are two very small tears on the back, and one of the corners is slightly chipped. Otherwise, this book is crisp, clean, and without flaw. Unsurpassed in comprehensiveness of text and richness of illustration, this book has become a byword for authority and beauty in its field. 1500 species described, 400 illustrations, 217 in full color.
